The general rule is "match what's around you."  So I guess that makes
it a drivers/pci/ rule.

Some of your messages are capitalized and others are not:

  dev_info(pci->dev, "Link failure\n"
  dev_err(dev, "Failed to get refclk clock: %ld\n"
  dev_err(dev, "Failed to get sysclk clock: %ld\n"
  dev_err(dev, "Failed to get auxclk clock: %ld\n"
  dev_err(dev, "interrupt intr is missing"
  dev_dbg(dev, "Applied default link speed\n"
  dev_dbg(dev, "link speed Gen %d"
  dev_err(dev, "Failed to initialize host\n"

I don't really care whether they're all capitalized or none are
capitalized, but they should all be the same.  Otherwise it just looks
sloppy.
